Six months after adventurer Dr Emmet Cole goes missing in the Amazon, his location beacon sends out a signal; Emmet's wife, Tess, along with her son and Emmet's film crew, embark on a journey to find him.

Dr Emmet Cole's spirit enters Jahel; the search party comes across a tree covered in dolls; a crew member goes missing.

When the crew of the Magus goes blind from tree spores, lone holdout AJ must overcome his most-paralysing fear to find a cure before the blindness becomes permanent; the local tribe stalks the crew and judges if they are worthy to stay in the jungle.

As the search for Emmet continues, the group finds one of his missing crew members exhibiting symptoms of a mystical curse; Lincoln tries to be the moral compass of the group.

The crew members become stranded and in need of some parts, but a ship that comes to their rescue presents an even greater danger.

The Magus crew finds Emmet's camera bag containing tapes, leading it further into the Amazon; Lena reveals a secret.
